Summary:Method and apparatus of video coding using coding modes including Intra Block Copy (IntraBC) for a video coding system incorporating multi-stage pipeline processing is disclosed. In order to overcome data dependency issue due to the use of pipeline architecture, a first embodiment uses constrained previous reconstructed region for IntraBC estimation by excluding unavailable reconstructed previous reconstructed data due to the multi-stage pipeline processing. In the second embodiment, the unavailable reconstructed data is replaced by source pixel data.
